A slope distance of 845.321 m was observed between two stations with EDM instruments having specified errors of ± (1.2 mm + 2 ppm). The instrument was centered with an estimated error of ± 1.9 mm. The estimated error in target miscentering was ± 2 mm. What is the estimated error in the observed distance?
